Stopping messenger chat politely

Chats gets boring many times and you want to interrupt conversation but stay polite.

How to do it?


1.After saying something unimportant close conversation window. It's a great chance that your co-speaker will not respond and that means end of conversation.

2.After your co-speaker say something not so important, close conversation window. Maybe no replay will not be so impolite and this will be the end of conversation.

3.Make your conversation longer&slower with short answers like:
Ok
yeah
maybe.
This will give you time to browse web and do things.

4.sorry gotta go. Different excuses like dinner, toilet and other will give you an excuse to quit conversation. Sorry gotta go website offer plenty of (funny) sounds usable in voice conversations.

5. spam person with links and promotions. Probably you do promote some ideas and when trying to stopping conversation, promoting&brainwashing is good thing to try.
